Yes, low density plastic tumbling media is commonly used in pre-anodizing surface preparation. One of the key requirements for anodizing is a clean, uniform surface free from burrs or tool marks, and plastic media excels at producing this type of finish—particularly on aluminum parts.

Because plastic media is less likely to embed or alter the surface chemistry of the part, it helps ensure that anodizing layers form evenly and adhere properly. It also reduces the risk of contamination or discoloration that can occur with more abrasive media types.

Ideal For:

  • Aluminum brackets and housings
  • Extrusions and CNC-machined aluminum parts
  • Die-cast aluminum components
